ROLLER WINDOW-SCREEN.

Application filed March 2, 1909. Serial No. 480,933.

To all whom it may concern:

Be it known that we, EDWARD H. GIBSON and ABRAM D. BEVIER, citizens of the United States, and residents of Clyde, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in Roller Window-Screens, of which the following is a specification.

Our invention relates to window-screens, and has for its object the provision of 'a screen having one edgemounted on a roller journaled in a suitable boxing and its opposite edge secured to the window-sill under the lower sash, said boxing having the width of the window-sash, and slidably mounted in the channel in the frame in which the sash is mounted. A metal tape is secured to each end of the roller and arranged to wind on the ends of the roller as the boxing is lifted, so as to hold the boxing in an adjusted position when raised, and when the boxing is lowered the tapes unwinding from the roller serve to rotate it to wrap the screen thereon. The free ends of the tapes are secured to springs at the top of the frame that hold the tapes taut at all times to compensate for the difference in thickness in the screen and tape on the roller.

The construction and operation of our improved window-screen will be described in detail hereinafter and illustrated in the accompanying drawings, in which- Figure 1 is a View of a window, showing our improved screen therein; Fig. 2, a crosssection, showing the lower end of the frame and sash and screen; Fig. 8, a detail view of the box and tapes; and Fig. &, a detail View, showing the roller removed from the box and tapes in position.

In the drawings similar reference characters indicate corresponding parts in all of the views.

The window frame or casing A is constructed in the usual manner and is provided with the beads B and C, formingthe channels for the sash D.

Our improvement consists of a boxing or.

housing 1, slidably mounted in the channel under the lower sash D, in which box is journaled a roller 2, having a length of wirescreen fabric 3 secured at one edge thereto, while its other edge isbent at an'angle, as

shown at 4, and secured to the window-sill E by any suitable fastenings 5.

Secured to the ends of roller 2 are tapes 6, made preferably of metal and arranged to wind on the roller in the contrary direction to the screen-fabric. The tapes 6 are extended through openings 7 in the ends of the boxing or housing 1 and up the frame between the front of the lower sash D and bead C, the upper ends of the tapes being secured to the free ends of leaf-springs 8, secured to the top of the frame A.

It will be understood that when the-device is in position, as shown, the sash D may be 7 raised independently of the screen, or, if desired, the housing 1 and sash may be raised simultaneously, unrolling the screen so as to cover the opening, or when the sash is raised the housing may be raised or lowered to screen 'the opening. When the housing is raised, it will'be apparent that the tapes 6 will be wound on the ends of the roller, so that in whatever position the housing is brought to rest it will be held in position, and when lowered the'tapes by unwinding from the roller will rotate it and wind the screen thereon, the springs 8 by holding the tapes taut at all times serving to retain the screen stretched and, as stated, compensating for the diiferences in thicknesses of the screen and tapes wound upon the roller.

Having thus described our invention, what we claim is- In combination with a window casing having a sill, and window-sashes mounted in said casing, a housing slidably mounted in said casing under the lower sash and independently thereof, a roller journaled in the housing, a screen secured to the roller and to the sill, tapes secured to the roller and arranged to wind thereon in a contrary direction to the screen, and leaf springs secured to the top of the window-casing and engaging thefree ends of the tapes to hold them taut, substantially as shown and described.

In witness whereof, we have hereunto set our hands in presence of two subscribing witnesses.
